If it's a one-off, how about using the export data wizard to export the tables out to CSV files (assuming you're using SQL Server, although I'm sure most databases have equivalents).
Once you've done this you can just do a 'Find Files' in explorer to find all occurrences?
It's a bit dirty - but it'll work!
